Use of performance measurement to include air quality and energy into mileage-based user fees

Use of performance measurement to include air quality and energy into mileage-based user fees

Date: March 2012
Creator: Farzaneh, Reza; Novak, Kristen; Baker, Richard T. & Goodin, Ginger
Description: "This research project is aimed at establishing a framework for levying MBUFs designed to achieve various air quality improvement policy objectives. This research presents the first step toward a pricing framework based on the concept of performance measurement that systematically defines and incorporates potential air quality goals. The process of developing the proposed framework included defining the interactive role of user fees and pricing in roadway transportation operations and identifying air quality performance measures for determining the appropriate vehicle mileage fee price."

Algorithms for routing vehicles and their application to the paratransit vehicle scheduling problem

Algorithms for routing vehicles and their application to the paratransit vehicle scheduling problem

Date: March 2012
Creator: Park, Myoungkuk; Oberlin, Paul; Rathinam, Sivakumar; Quadrifoglio, Luca & Darbha, Swaroop
Description: "As the demand for paratransit services increases, there is a constant pressure to maintain the quality of service provided to the customers while minimizing the cost of operation: this is especially important as the availability of public funding for paratransit services has been on the decline. Key tasks in accomplishing this objective are efficiently allocating vehicles to service trips and adjusting the schedules of vehicles dynamically in response to calls received by the service providers from the customers on the day of the service."

Multi-vehicle mobility allowance shuttle transit (MAST) system: an analytical model to select the fleet size and a scheduling heuristic

Multi-vehicle mobility allowance shuttle transit (MAST) system: an analytical model to select the fleet size and a scheduling heuristic

Date: June 2012
Creator: Quadrifoglio, Luca & Lu, Wei
Description: This report discusses the mobility allowance shuttle transit (MAST) system which is a hybrid transit system in which vehicles are allowed to deviate from a fixed rout to serve flexible demand. The mixed interfere programming (MIP) formulation analyzed the impacts of time headways between consecutive transit vehicles on the performance of a two-vehicle MAST system. An analytical framework is then developed to model the performance of both one-vehicle and two-vehicle MAST systems, which is used to identify the critical demand level at which an increase of the fleet size from one to two vehicles would be appropriate. From this research an insertion heuristic for a multi-vehicle MAST system was developed.

Development of statistical models to forecast crossing times of commercial vehicles

Development of statistical models to forecast crossing times of commercial vehicles

Date: July 2011
Creator: Kang, Dong Hun; Ochoa, Cesar; Rajbhandari, Rajat & Garcia, Francisco
Description: In this report statistical models were developed to predict crossing times of trucks over a short range of time. The statistical prediction models use historic data and take into account empirical relationships between border-crossing-related parameters and truck crossing times.

Evaluating the use of transfers for improving rural public transportation systems

Evaluating the use of transfers for improving rural public transportation systems

Date: August 2011
Creator: Quadrifoglio, Luca; Shen, Chung-Wei & Edrington, Suzie
Description: "In this report researchers consider a variation of the regular demand responsive transit system that adopts the transfer practice to reduce operating costs.Researchers evaluated the effect of different transfer operating policies by developing a simulation model of several plausible scenarios. The results indicate that zoning with transfer can provide significant benefits paratransit operations that are managing zoning structure."

The value of public transportation for improving the quality of life for the rural elderly

The value of public transportation for improving the quality of life for the rural elderly

Date: July 2012
Creator: Mjelde, James W.; Dudensing, Rebekka; Cherrington, Linda Kay; Yanhong, Jin; Israel, Alicia A. & Chen, Junyi
Description: "This report focuses on non-medical transportation; medical transportation is addressed in the literature and is more widely available to the elderly. Because expanded rural transportation systems likely will be funded by taxpayers, an understanding of their preferences and willingness-to-pay for non-medical transportation options is essential."
